Description

この発明は、固定体に支持された可動体の少なくとも往動を、所定移動位置より移動終了位置まで、付勢手段によって補助する機構の改良に関する。   The present invention relates to an improvement in a mechanism that assists at least forward movement of a movable body supported by a fixed body from a predetermined movement position to a movement end position by a biasing means.

扉を閉じるときに、この扉の所定回動位置より閉じきった位置まで、付勢手段によってこの扉の回動を補助する機構として、本出願人が先に開示した特願２００６−３３２２３７にかかる機構がある。   Japanese Patent Application No. 2006-332237 previously disclosed by the present applicant as a mechanism for assisting the rotation of the door by the biasing means until the door is completely closed from the predetermined rotation position when the door is closed. There is a mechanism.

また、引き戸を閉じるときに、この引き戸の所定移動位置より閉じきった位置まで、付勢手段によってこの引き戸の移動を補助する機構として、本出願人が先に開示した特願２００７−１０１６２９にかかる機構がある。   Further, as a mechanism for assisting the movement of the sliding door by the urging means from the predetermined movement position of the sliding door when the sliding door is closed, the present applicant applies to Japanese Patent Application No. 2007-101629 previously disclosed. There is a mechanism.

特願２００６−３３２２３７にかかる機構では、可動体としての扉に備えられるストライカ部材と、固定体としての扉枠に備えられるキャッチャー部材とを有している。   The mechanism according to Japanese Patent Application No. 2006-332237 includes a striker member provided in a door as a movable body and a catcher member provided in a door frame as a fixed body.

特願２００７−１０１６２９にかかる機構では、固定体としての戸枠に備えられるストライカ部材と、可動体としての引き戸に備えられるキャッチャー部材とを有している。   The mechanism according to Japanese Patent Application No. 2007-101629 includes a striker member provided in a door frame as a fixed body and a catcher member provided in a sliding door as a movable body.

いずれの機構においても、キャッチャー部材は、待機位置と引き込み位置との間に亘る移動可能に備えられると共に、待機位置においては付勢手段に蓄勢させた状態で保持手段によってこの待機位置に位置づけられるようになっており、そして、所定移動（ないしは回動）位置に可動体を往動させたときに、ストライカ部材は待機位置に位置づけられたキャッチャー部材に捕捉掛合され、続いて保持手段による保持が解除されてキャッチャー部材は引き込み位置まで付勢手段の付勢により移動又は相対的に移動されてこの付勢力を移動終了位置まで可動体に作用させるようになっている。   In any of the mechanisms, the catcher member is provided so as to be movable between the standby position and the retracted position, and in the standby position, the catcher member is positioned in the standby position by the holding means while being stored in the biasing means. When the movable body is moved forward to a predetermined movement (or rotation) position, the striker member is caught and engaged with the catcher member positioned at the standby position, and subsequently held by the holding means. After being released, the catcher member is moved or relatively moved to the retracted position by the urging means, and this urging force is applied to the movable body to the movement end position.

ここで、これらの機構においては、所定移動位置に可動体が往動されていない状態から、誤って保持手段によるキャッチャー部材の保持を解除してしまうと、キャッチャー部材は前記付勢によりストライカ部材を捕捉しない状態で引き込み位置に移動してしまう。こうした場合には、可動体を移動終了位置まで移動させて引き込み位置にあるキャッチャー部材にストライカ部材を捕捉掛合させることで所期の状態への復帰が図られる。しかるに、固定体に対する可動体の組み付けないし組み合わせ状態がなんらかの理由で損なわれてしまっている場合、例えば、固定体としての扉枠や可動体としての扉に狂いが生じた場合などの場合、可動体を移動終了位置まで移動させても引き込み位置にあるキャッチャー部材の掛合箇所にストライカ部材を入り込ませることができなくなる。   Here, in these mechanisms, when the movable body is not moved forward to the predetermined moving position, if the catcher member is erroneously released from being held by the holding means, the catcher member causes the striker member to move by the biasing force. It moves to the retracted position without being captured. In such a case, the movable body is moved to the movement end position, and the striker member is captured and engaged with the catcher member at the retracted position, thereby returning to the intended state. However, when the assembly or combination state of the movable body with respect to the fixed body has been damaged for some reason, for example, when the door frame as the fixed body or the door as the movable body is out of order, the movable body Even if it is moved to the movement end position, the striker member cannot be inserted into the catching portion of the catcher member at the retracted position.

この発明が解決しようとする主たる問題点は、この種の機構において前記のように誤って保持手段によるキャッチャー部材の保持を解除してしまった場合の所期の状態への復帰を、固定体に対する可動体の組み付けないし組み合わせ状態がなんらかの理由で損なわれてしまっている場合であっても容易且つ確実になさせるようにする点にある。   The main problem to be solved by the present invention is that, in this type of mechanism, when the holding of the catcher member by the holding means is erroneously released as described above, the return to the intended state is performed on the fixed body. Even if the assembly or combination state of the movable body has been damaged for some reason, it is easy and reliable.

前記課題を達成するために、この発明にあっては、可動体のアシスト装置を、以下の（１）〜（５）の構成を備えたものとした。
（１）固定体に支持された可動体の少なくとも往動を、所定移動位置より移動終了位置まで、付勢手段によって補助する可動体のアシスト装置であって、
（２）固定体及び可動体のいずれか一方に備えられるストライカ部材と、これらの他方に備えられるキャッチャー部材とを有しており、
（３）キャッチャー部材は、待機位置と引き込み位置との間に亘る移動可能に備えられると共に、待機位置においては付勢手段に蓄勢させた状態で保持手段によってこの待機位置に位置づけられるようになっており、
（４）所定移動位置に可動体を往動させたときに、ストライカ部材は待機位置に位置づけられたキャッチャー部材に捕捉掛合され、続いて保持手段による保持が解除されてキャッチャー部材は引き込み位置まで付勢手段の付勢により移動又は相対的に移動されてこの付勢力を移動終了位置まで可動体に作用させるようになっており、
（５）しかも、ストライカ部材を捕捉しない状態で引き込み位置に移動されたキャッチャー部材を待機位置に向けて移動操作可能とする操作手段を備えている。 In order to achieve the above object, according to the present invention, the movable body assist device has the following configurations (1) to (5).
(1) A movable body assist device that assists at least forward movement of a movable body supported by a fixed body from a predetermined movement position to a movement end position by an urging means,
(2) It has a striker member provided in one of the fixed body and the movable body, and a catcher member provided in the other of these,
(3) The catcher member is provided so as to be movable between the standby position and the retracted position, and in the standby position, the catcher member is positioned at the standby position by the holding means while being stored in the biasing means. And
(4) When the movable body is moved forward to the predetermined movement position, the striker member is caught by the catcher member positioned at the standby position, and then the holding by the holding means is released, and the catcher member is attached to the retracted position. It is moved or relatively moved by the urging means, and this urging force is applied to the movable body to the movement end position.
(5) In addition, an operation means is provided that enables the catcher member that has been moved to the retracted position without capturing the striker member to be moved toward the standby position.

所定移動位置に可動体が往動されていない状態から、誤って保持手段によるキャッチャー部材の保持を解除してしまうと、キャッチャー部材は前記付勢によりストライカ部材を捕捉しない状態で引き込み位置に移動してしまう。こうした場合には、可動体を移動終了位置まで移動させて引き込み位置にあるキャッチャー部材にストライカ部材を捕捉掛合させることで所期の状態への復帰が図られる。しかるに、固定体に対する可動体の組み付けないし組み合わせ状態がなんらかの理由で損なわれてしまっている場合、例えば、固定体としての扉枠や可動体としての扉に狂いが生じた場合などの場合、可動体を移動終了位置まで移動させても引き込み位置にあるキャッチャー部材の掛合箇所にストライカ部材を入り込ませることができなくなる。この発明にかかるアシスト装置にあっては、このような場合でも、操作手段によって前記狂いなどの寸法分キャッチャー部材を待機位置に向けて移動させてキャッチャー部材にストライカ部材を捕捉掛合させることができる。   If holding of the catcher member by the holding means is mistakenly released from the state where the movable body is not moved forward to the predetermined movement position, the catcher member moves to the retracted position without capturing the striker member due to the biasing. End up. In such a case, the movable body is moved to the movement end position, and the striker member is captured and engaged with the catcher member at the retracted position, thereby returning to the intended state. However, when the assembly or combination state of the movable body with respect to the fixed body has been damaged for some reason, for example, when the door frame as the fixed body or the door as the movable body is out of order, the movable body Even if it is moved to the movement end position, the striker member cannot be inserted into the catching portion of the catcher member at the retracted position. In the assist device according to the present invention, even in such a case, the striker member can be captured and engaged with the catcher member by moving the catcher member toward the standby position by the operating means by the dimension such as the deviation.

前記ストライカ部材を、ストライカベースと、このストライカベースから付勢によって引き込み可能に突出したストライカ軸とから構成させ、
キャッチャー部材を、回動体として構成されていると共に、その外周において開放されてその回動中心側に向けて続くストライカ軸の掛合凹部を備えたものとし、
所定移動位置に可動体を往動させたときに待機位置にあるキャッチャー部材のこの掛合凹部にストライカ軸が入り込み、これに続く付勢手段の付勢によるキャッチャー部材の引き込み位置への回動によりこの付勢力を移動終了位置まで可動体に作用させるようになっていると共に、
ストライカ部材を捕捉しない状態で引き込み位置にキャッチャー部材が移動された状態において、掛合凹部の側方箇所へのストライカ軸の当接に伴う付勢に抗したこのストライカ軸の引き込みによるこの掛合凹部の側方箇所のストライカ軸の乗り越えによって、移動終了位置に向けた可動体の往動を許容させるようにしておくこともある。 The striker member is composed of a striker base and a striker shaft protruding from the striker base so as to be retractable by urging.
The catcher member is configured as a rotating body, and has a striker shaft engagement recess that is opened at the outer periphery and continues toward the rotation center side,
When the movable body is moved forward to the predetermined moving position, the striker shaft enters the engaging recess of the catcher member at the standby position, and the catcher member is then rotated to the retracted position by the urging force of the urging means. The urging force is applied to the movable body up to the movement end position,
In the state where the catcher member is moved to the retracted position without capturing the striker member, the side of the engagement recess by pulling of the striker shaft against the urging force caused by the contact of the striker shaft with the side portion of the engagement recess In some cases, the movement of the movable body toward the movement end position is permitted by overcoming the striker shaft in one direction .

ストライカ部材を捕捉しない状態で引き込み位置にキャッチャー部材が移動された場合、可動体を移動終了位置まで往動させるとストライカ部材における掛合凹部の側方箇所にストライカ軸が突き当たって前記付勢に抗してストライカ軸が一旦引き込みストライカ軸の突き出し端の側方箇所の乗り越えが許容される。そして、この乗り越え後に前記付勢によりストライカ軸は再び前記付勢により突出して引き込み位置にあるキャッチャー部材の掛合凹部に入り込み捕捉掛合される。固定体としての扉枠に対する可動体としての扉の組み付けないし組み合わせ状態に狂いなどが生じている場合、扉を移動終了位置まで移動させても引き込み位置にあるキャッチャー部材の掛合凹部にストライカ部材のストライカ軸を入り込ませることができなくなる。かかるアシスト装置にあっては、このような場合でも、操作手段によって、キャッチャー部材の掛合凹部にストライカ部材のストライカ軸が入り込む位置まで、前記狂いなどの寸法分キャッチャー部材を待機位置に向けて回動させることができる。   When the catcher member is moved to the retracted position without capturing the striker member, when the movable body is moved forward to the movement end position, the striker shaft strikes a side portion of the engaging recess in the striker member to resist the bias. Thus, the striker shaft is once retracted, and the side portion of the protruding end of the striker shaft is allowed to pass over. Then, after overcoming the striker shaft, the striker shaft again protrudes by the biasing force and enters the catching recess of the catcher member in the retracted position by the biasing force. When the door as a movable body is assembled to the door frame or the assembled state is out of order, even if the door is moved to the movement end position, the striker of the striker member is inserted into the catching recess of the catcher member at the retracted position. The shaft cannot be inserted. In such an assist device, even in such a case, the catcher member is rotated by the operating means toward the standby position by the dimension such as the deviation until the striker shaft of the striker member enters the engaging recess of the catcher member. Can be made.

この発明にかかるアシスト装置によれば、前記のように誤って保持手段によるキャッチャー部材の保持を解除してしまった場合の所期の状態への復帰を、固定体に対する可動体の組み付けないし組み合わせ状態がなんらかの理由で損なわれてしまっている場合であっても容易且つ確実になすことができる。   According to the assist device according to the present invention, when the holding of the catcher member by the holding means is erroneously released as described above, the return to the intended state is performed by assembling or combining the movable body with the fixed body. Even if it is damaged for some reason, it can be done easily and reliably.

This shows the state that is no longer possible. 17 shows a first example of a configuration example of the operating means 5 for eliminating the state of FIG. 16, FIG. 18 shows a second example thereof, FIG. 19 shows a third example thereof, and FIG. 20 shows a fourth example thereof. Each is shown.

この実施の形態にかかる可動体のアシスト装置は、固定体Ｓに支持された可動体Ｍの少なくとも往動を、所定移動位置より移動終了位置まで、付勢手段３によって補助するものである。   The assist device for a movable body according to this embodiment assists at least the forward movement of the movable body M supported by the fixed body S from the predetermined movement position to the movement end position by the urging means 3.

かかるアシスト装置は、典型的には、扉Ｍａや開き戸などの回動するものや、引き戸Ｍｂや吊り戸などのスライド移動するものなどを可動体Ｍとして、使用できるものである。   Such an assist device can typically use, as the movable body M, a rotating device such as a door Ma or a hinged door, or a sliding device such as a sliding door Mb or a hanging door.

かかるアシスト装置は、固定体Ｓ及び可動体Ｍのいずれか一方に備えられるストライカ部材１と、これらの他方に備えられるキャッチャー部材２とを有している。    The assist device includes a striker member 1 provided on one of the fixed body S and the movable body M, and a catcher member 2 provided on the other of these.

キャッチャー部材２は、待機位置と引き込み位置との間に亘る移動可能に備えられると共に、待機位置においては付勢手段３に蓄勢させた状態で保持手段４によってこの待機位置に位置づけられるようになっている。そして、所定移動位置に可動体Ｍを往動させたときに、ストライカ部材１は待機位置に位置づけられたキャッチャー部材２に捕捉掛合され、続いて保持手段４による保持が解除されてキャッチャー部材２は引き込み位置まで付勢手段３の付勢により移動又は相対的に移動されてこの付勢力を移動終了位置まで可動体Ｍに作用させるようになっている。   The catcher member 2 is provided so as to be movable between a standby position and a retracted position, and in the standby position, the catcher member 2 is positioned at this standby position by the holding means 4 while being stored in the biasing means 3. ing. When the movable body M is moved forward to a predetermined movement position, the striker member 1 is caught and engaged with the catcher member 2 positioned at the standby position, and subsequently the holding by the holding means 4 is released, and the catcher member 2 is It is moved or relatively moved by the urging force of the urging means 3 to the retracted position, and this urging force is applied to the movable body M to the movement end position.

これにより、かかるアシスト装置によれば、所定移動位置まで往動させた可動体Ｍを、この所定移動位置でストライカ部材１を捕捉（キャッチ）した状態で前記付勢により引き込み位置に移動又は相対的に移動されるキャッチャー部材２によって、移動終了位置まで移動させるようにすることができる。このように移動終了位置に移動された可動体Ｍを復動させると、ストライカ部材１を捕捉して引き込み位置にあるキャッチャー部材２は付勢手段３に蓄勢させながら待機位置まで移動又は相対的に移動され待機位置において保持手段４に再び位置づけられると共に、ストライカ部材１の捕捉掛合を解く。（リリース）   Thus, according to the assist device, the movable body M moved forward to the predetermined movement position is moved or relatively moved to the retracted position by the urging while the striker member 1 is captured (caught) at the predetermined movement position. It can be made to move to the movement end position by the catcher member 2 moved to the position. When the movable body M thus moved to the movement end position is moved backward, the striker member 1 is captured and the catcher member 2 in the retracted position moves to the standby position while being stored in the urging means 3 or relatively. And is again positioned at the holding means 4 in the standby position, and the catching engagement of the striker member 1 is released. (release)

それと共に、この実施の形態にかかるアシスト装置は、ストライカ部材１を捕捉しない状態で引き込み位置に移動されたキャッチャー部材２を待機位置に向けて移動操作可能とする操作手段５を備えている。   At the same time, the assist device according to this embodiment includes an operation means 5 that enables the catcher member 2 that has been moved to the retracted position without capturing the striker member 1 to be moved toward the standby position.

所定移動位置に可動体Ｍが往動されていない状態から、誤って保持手段４によるキャッチャー部材２の保持を解除してしまうと、キャッチャー部材２は前記付勢によりストライカ部材１を捕捉しない状態で引き込み位置に移動してしまう。こうした場合には、可動体Ｍを移動終了位置まで移動させて引き込み位置にあるキャッチャー部材２にストライカ部材１を捕捉掛合させることで所期の状態への復帰が図られる。しかるに、固定体Ｓに対する可動体Ｍの組み付けないし組み合わせ状態がなんらかの理由で損なわれてしまっている場合、例えば、固定体Ｓとしての扉Ｍａ枠や可動体Ｍとしての扉Ｍａに狂いが生じた場合などの場合、可動体Ｍを移動終了位置まで移動させても引き込み位置にあるキャッチャー部材２の掛合箇所にストライカ部材１を入り込ませることができなくなる。この実施の形態にかかるアシスト装置にあっては、このような場合でも、操作手段５によって前記狂いなどの寸法分キャッチャー部材２を待機位置に向けて移動させてキャッチャー部材２にストライカ部材１を捕捉掛合させることができる。   If holding of the catcher member 2 by the holding means 4 is mistakenly released from the state where the movable body M is not moved forward to the predetermined movement position, the catcher member 2 does not capture the striker member 1 by the biasing. It will move to the retracted position. In such a case, the movable body M is moved to the movement end position, and the striker member 1 is captured and engaged with the catcher member 2 in the retracted position, thereby returning to the intended state. However, when the assembly or combination state of the movable body M with respect to the fixed body S has been damaged for some reason, for example, when the door Ma frame as the fixed body S or the door Ma as the movable body M is out of order. In such a case, even if the movable body M is moved to the movement end position, the striker member 1 cannot be inserted into the catching position of the catcher member 2 at the retracted position. In the assist device according to this embodiment, even in such a case, the catcher member 2 is moved toward the standby position by the operating means 5 by the dimension such as the deviation, and the striker member 1 is captured by the catcher member 2. Can be hooked.

（図１〜図９に示される例）
図１〜図９は、かかるアシスト装置によって、扉Ｍａの往動（閉じる向きの回動）を、所定移動位置（扉Ｍａが閉じる直前の位置）より移動終了位置（扉Ｍａが閉じきった位置）まで補助するようにしてある。図示の例では、可動体Ｍは扉Ｍａであり、固定体Ｓは扉枠Ｓａとなっている。また、図示の例では、キャッチャー部材２は扉枠Ｓａの上枠部Ｓｂの下面に取り付けられ、こらに対応してストライカ部材１は扉Ｍａの上部に取り付けられている。 (Example shown in FIGS. 1 to 9)
1 to 9 show that the assist device moves the door Ma forward (turning in the closing direction) from a predetermined movement position (position just before the door Ma closes) to a movement end position (a position where the door Ma is completely closed). ). In the illustrated example, the movable body M is a door Ma, and the fixed body S is a door frame Sa. In the illustrated example, the catcher member 2 is attached to the lower surface of the upper frame portion Sb of the door frame Sa, and the striker member 1 is attached to the upper portion of the door Ma correspondingly.

この例では、ストライカ部材１は、ストライカベース１０と、このストライカベース１０から付勢によって引き込み可能に突出したストライカ軸１１とから構成されている。ストライカベース１０は、その一端を扉Ｍａに止着させると共に、その他端に上方に向けて突き出すストライカ軸１１の収容筒部１０ａを有しており、（図５）ストライカ軸１１はこの収容筒部１０ａの開放された筒上端１０ｂから前記付勢によりその上端を上方に向けて突き出させるように構成されている。   In this example, the striker member 1 includes a striker base 10 and a striker shaft 11 protruding from the striker base 10 so as to be retractable by urging. The striker base 10 has one end of the striker base 10 fixed to the door Ma, and the other end has an accommodating cylinder portion 10a of the striker shaft 11 protruding upward (FIG. 5). The upper end of the cylinder 10b opened from 10a is projected upward by the biasing.

一方、キャッチャー部材２は、ストライカ軸１１の軸線に沿う向きに回動軸２０ａを配した回動体２０として構成されていると共に、その外周において開放されてその回動中心側に向けて続くストライカ軸１１の掛合凹部２０ｂを備えており、所定移動位置に可動体Ｍとしての扉Ｍａを往動させたときに待機位置（図３の位置）にあるキャッチャー部材２のこの掛合凹部２０ｂにストライカ軸１１が入り込み、これに続く付勢手段３の付勢によるキャッチャー部材２の引き込み位置（図４の位置）への回動によりこの付勢力を移動終了位置まで扉Ｍａに作用させるようになっている。移動終了位置から扉Ｍａを復動させるとキャッチャー部材２は再び待機位置まで回動され保持手段４によりその位置に再び位置づけられると共にストライカ軸１１をリリースする。   On the other hand, the catcher member 2 is configured as a rotating body 20 having a rotating shaft 20a disposed in a direction along the axis of the striker shaft 11, and is opened on the outer periphery thereof and continues toward the rotating center side. 11 is provided with the engaging recess 20b of the catcher member 2 in the standby position (position of FIG. 3) when the door Ma as the movable body M is moved forward to a predetermined movement position. Then, the urging force is applied to the door Ma by the rotation of the catcher member 2 to the retracted position (position shown in FIG. 4) by the urging force of the urging means 3 following this. When the door Ma is moved backward from the movement end position, the catcher member 2 is again rotated to the standby position and is again positioned at that position by the holding means 4 and the striker shaft 11 is released.

そしてこの例では、ストライカ部材１を捕捉しない状態で引き込み位置にキャッチャー部材２が移動された状態において、ストライカ部材１における掛合凹部２０ｂの側方箇所２０ｃへの当接に伴う付勢に抗したストライカ軸１１の引き込みによって移動終了位置に向けた可動体Ｍの往動を許容させるようになっている。かかる側方箇所２０ｃの下面側にはかかる引き込みを可能ならしめる傾斜面２０ｄが形成されている。   In this example, in a state where the striker member 1 is not captured and the catcher member 2 is moved to the retracted position, the striker resists the bias associated with the contact of the engaging recess 20b with the side portion 20c of the striker member 1. The forward movement of the movable body M toward the movement end position is allowed by the retraction of the shaft 11. An inclined surface 20d is formed on the lower surface side of the side portion 20c to enable the pull-in.

この例では、ストライカ部材１を捕捉しない状態で引き込み位置にキャッチャー部材２が移動された場合、可動体Ｍを移動終了位置まで往動させるとストライカ部材１における掛合凹部２０ｂの側方箇所２０ｃにストライカ軸１１が突き当たって前記付勢に抗してストライカ軸１１が一旦引き込みストライカ軸１１の突き出し端の側方箇所２０ｃの乗り越えが許容されるようになっている。そして、この乗り越え後に前記付勢によりストライカ軸１１は再び前記付勢により突出して引き込み位置にあるキャッチャー部材２の掛合凹部２０ｂに入り込み捕捉掛合されるようになっている。固定体Ｓとしての扉枠Ｓａに対する可動体Ｍとしての扉Ｍａの組み付けないし組み合わせ状態に狂いなどが生じている場合、扉Ｍａを移動終了位置まで移動させても引き込み位置にあるキャッチャー部材２の掛合凹部２０ｂにストライカ部材１のストライカ軸１１を入り込ませることができなくなる。（図５、図６（ｂ））この例にかかるアシスト装置にあっては、このような場合でも、操作手段５によって、キャッチャー部材２の掛合凹部２０ｂにストライカ部材１のストライカ軸１１が入り込む位置まで、前記狂いなどの寸法分キャッチャー部材２を待機位置に向けて回動させることができる。（図７）   In this example, when the catcher member 2 is moved to the retracted position without capturing the striker member 1, when the movable body M is moved forward to the movement end position, the striker is placed on the side portion 20c of the engaging recess 20b in the striker member 1. The striker shaft 11 is once retracted against the urging when the shaft 11 strikes, so that the side portion 20c of the projecting end of the striker shaft 11 is allowed to get over. Then, the striker shaft 11 protrudes again by the urging force after entering the catching recess 20b of the catcher member 2 in the retracted position by the urging, and is caught. When the door Ma as the movable body M is assembled or assembled to the door frame Sa as the fixed body S, the catcher member 2 is in the retracted position even if the door Ma is moved to the movement end position. The striker shaft 11 of the striker member 1 cannot enter the recess 20b. (FIGS. 5 and 6B) In the assist device according to this example, even in such a case, the position where the striker shaft 11 of the striker member 1 enters the engaging recess 20b of the catcher member 2 by the operation means 5. Until then, the catcher member 2 can be rotated toward the standby position by the dimension such as the deviation. (Fig. 7)

図示の例では、キャッチャー部材２は、上面を扉枠Ｓａの上枠部Ｓｂの下面への取り付け面６０ａとしたケーシング６０に前記回動を可能とした状態で組み合わされ納められている。ケーシング６０は下面を開放させた細長い箱状をなすように構成されている。キャッチャー部材２は、このケーシング６０の一端６０ｂ側に偏った位置に備えられている。ケーシング６０におけるこのキャッチャー部材２の配設箇所の側方には待機位置にあるキャッチャー部材２の掛合凹部２０ｂの形成箇所が突き出される開放部６０ｃが形成されている。   In the illustrated example, the catcher member 2 is combined and stored in a casing 60 whose upper surface is an attachment surface 60a to the lower surface of the upper frame portion Sb of the door frame Sa in a state where the rotation is possible. The casing 60 is configured to have an elongated box shape with the lower surface opened. The catcher member 2 is provided at a position biased toward the one end 60 b side of the casing 60. An opening 60c is formed on the side of the casing 60 where the catcher member 2 is disposed, from which a portion where the catching recess 20b of the catcher member 2 at the standby position is formed protrudes.

キャッチャー部材２は、その回動軸２０ａの形成側を要部とする扇形体２０ｅに、その弧状縁２０ｆにおいて溝一端を開放させてこの回動軸２０ａ（つまり回動中心側）に続く割溝状をなす掛合凹部２０ｂを形成させることにより構成されている。キャッチャー部材２における掛合凹部２０ｂは前記扇形体２０ｅの一方の直線状縁２０ｇに偏った位置に設けられており、キャッチャー部材２のこの掛合凹部２０ｂと扇形体２０ｅの他方の直線状縁２０ｈとの間に亘る弧状縁２０ｆには、ケーシング６０の長さ方向にスライド可能にこのケーシング６０に支持組み合わされたスライダ７０における、このスライダ７０のスライド方向に沿うように設けられたラック７０ａにかみ合うギア部２０ｉが形成されている。   The catcher member 2 has a fan-shaped body 20e whose main part is the side on which the rotation shaft 20a is formed, with one end of the groove opened at the arcuate edge 20f, and the split groove continuing to the rotation shaft 20a (that is, the rotation center side). It is comprised by forming the latching recessed part 20b which makes a shape. The catching recess 20b in the catcher member 2 is provided at a position biased to one linear edge 20g of the sector 20e, and the catching recess 20b of the catcher member 2 and the other linear edge 20h of the sector 20e. An arcuate edge 20f extending between the gears meshes with a rack 70a provided along the sliding direction of the slider 70 in the slider 70 supported and combined with the casing 60 so as to be slidable in the length direction of the casing 60. 20i is formed.

ケーシング６０におけるその他端６０ｄとキャッチャー部材２との間には、かかるスライダ７０のラック７０ａにかみ合うピニオン８０が備えられている。また、ケーシング６０には、バネ一端３０ｂをケーシング６０の他端６０ｄ側に止着させ、かつ、バネ他端３０ａを連係パーツ９０を介在させてピニオン８０に接続させた付勢手段３としての引っ張りコイルバネ３０が備えられている。連係パーツ９０はピニオン８０の回転軸に偏心した位置においてピニオン８０に枢支されている。そして、図示の例では、ピニオン８０の回転中心８０ｂと前記引っ張りコイルバネ３０のバネ一端３０ｂの止着箇所を通る仮想の直線ｘ上に前記枢支部８０ａが位置されたときはこのバネ３０がもっとも引き延ばされると共に、この仮想の直線ｘよりも後方に前記枢支部８０ａが位置されるときはスライダ７０はケーシング６０の他端６０ｄ側にもっとも移動されこの状態においてキャッチャー部材２は前記バネ３０により待機位置に位置づけられ、（図３）一方、前記仮想の直線ｘよりも前方に前記枢支部８０ａが位置されるときはスライダ７０はケーシング６０の一端６０ｂ側にもっとも移動されこの状態においてキャッチャー部材２は前記バネ３０により引き込み位置に位置づけられるようになっている。（図４）すなわち、この例では、かかるバネ３０とピニオン８０とにより前記保持手段４を構成させている。   A pinion 80 that engages with the rack 70 a of the slider 70 is provided between the other end 60 d of the casing 60 and the catcher member 2. Further, the casing 60 has a spring end 30b fixed to the other end 60d side of the casing 60, and the spring other end 30a is connected to the pinion 80 with the linkage part 90 interposed therebetween. A coil spring 30 is provided. The linkage part 90 is pivotally supported by the pinion 80 at a position eccentric to the rotation axis of the pinion 80. In the illustrated example, when the pivotal support 80a is positioned on an imaginary straight line x passing through the fastening center of the rotation center 80b of the pinion 80 and the spring end 30b of the tension coil spring 30, the spring 30 is pulled most. When the pivot portion 80a is positioned behind the imaginary straight line x, the slider 70 is moved most toward the other end 60d of the casing 60. In this state, the catcher member 2 is moved to the standby position by the spring 30. (FIG. 3), on the other hand, when the pivotal support 80a is positioned in front of the virtual straight line x, the slider 70 is moved most toward the one end 60b of the casing 60, and in this state, the catcher member 2 is The spring 30 is positioned at the retracted position. That is, in this example, the holding means 4 is constituted by the spring 30 and the pinion 80.

ケーシング６０の一端６０ｂ側には、ボタン体５０を上下動可能に支持する支持部６０ｅが形成されている。支持部６０ｅは下方にボタン体５０の突きだし開口６０ｆを、側方にスライダ７０の端部の入れ込み開口６０ｇをそれぞれ備えている。ボタン体５０は支持部６０ｅの奥部６０ｈとボタン体５０の内端５０ａとの間に介装されたバネ６０ｉによりあご部５０ｂを支持部６０ｅの突きだし開口６０ｆの内縁に引っかけた状態でその外端を支持部６０ｅから突き出させている。ボタン体５０における入れ込み開口６０ｇに向けられた側には下方に向かうに連れてボタン体５０の移動中心軸から次第に離れ出す向きの傾斜状をなすスライダ７０の端部７０ｂへの突き当たり面５０ｃが形成されている。そして、図示の例では、キャッチャー部材２が待機位置にあるとき、スライダ７０の端部７０ｂが支持部６０ｅ内に入り込み、ボタン体５０の突き当たり面５０ｃの上方に位置されるようになっている。（図６（ａ））   On the one end 60b side of the casing 60, a support portion 60e that supports the button body 50 so as to be movable up and down is formed. The support portion 60e is provided with a protruding opening 60f of the button body 50 on the lower side, and an insertion opening 60g at the end of the slider 70 on the side. The button body 50 is outside in a state in which the jaw part 50b is hooked on the inner edge of the protruding opening 60f of the support part 60e by a spring 60i interposed between the back part 60h of the support part 60e and the inner end 50a of the button body 50. The end is protruded from the support part 60e. On the side of the button body 50 facing the insertion opening 60g, an abutting surface 50c against the end portion 70b of the slider 70 is formed so as to gradually move away from the moving central axis of the button body 50 as it goes downward. Has been. In the illustrated example, when the catcher member 2 is in the standby position, the end portion 70b of the slider 70 enters the support portion 60e and is positioned above the abutting surface 50c of the button body 50. (Fig. 6 (a))

扉枠Ｓａに対する扉Ｍａの組み付けないし組み合わせ状態に狂いなどが生じていて、ストライカ部材１を捕捉しない状態で引き込み位置にキャッチャー部材２が移動された場合において扉Ｍａを移動終了位置まで移動させても引き込み位置にあるキャッチャー部材２の掛合凹部２０ｂにストライカ部材１のストライカ軸１１を入り込ませることができないとき、（図５、図６（ｂ））前記ボタン体５０を上方に押し込み操作するとスライダ７０をケーシング６０の他端６０ｄ側に若干移動させてこれに伴ってキャッチャー部材２をその掛合凹部２０ｂにストライカ部材１のストライカ軸１１を入り込ませるまで待機位置に向けてやや回動させることができる。（図７）すなわち、この例にあっては、かかるボタン体５０が前記操作手段５として機能するようになっている。そして、この操作手段５としてのボタン体５０が、付勢手段３としての前記バネ３０の付勢力をキャッチャー部材２に伝達する伝達部材としてのスライダ７０を介して、キャッチャー部材２を待機位置に向けて移動させるようになっている。   Even when the door Ma is moved to the end position when the catcher member 2 is moved to the retracted position in a state where the door Ma is assembled to or assembled with the door frame Sa and the striker member 1 is not captured. When the striker shaft 11 of the striker member 1 cannot be inserted into the engaging recess 20b of the catcher member 2 in the retracted position (FIGS. 5 and 6B), the slider 70 is moved by pushing the button body 50 upward. The catcher member 2 can be slightly rotated toward the standby position until the striker shaft 11 of the striker member 1 is inserted into the engaging recess 20b. That is, in this example, the button body 50 functions as the operation means 5 (FIG. 7). The button body 50 as the operation means 5 directs the catcher member 2 to the standby position via the slider 70 as a transmission member for transmitting the urging force of the spring 30 as the urging means 3 to the catcher member 2. To be moved.

図８は、伝達部材としてのスライダ７０自体に下方に突き出すつまみ部５１を形成させ、このつまみ部５１を利用したラック７０ａの移動により引き込み位置にあるキャッチャー部材２を待機位置に向けて回動させるようにした例を示している。すなわち、この例にあっては、かかるつまみ部５１が前記操作手段５として機能するようになっている。   In FIG. 8, a slider portion 51 that protrudes downward is formed on the slider 70 itself as a transmission member, and the catcher member 2 in the retracted position is rotated toward the standby position by the movement of the rack 70 a using the knob portion 51. An example is shown. That is, in this example, the knob portion 51 functions as the operation means 5.

また、図９は、キャッチャー部材２自体にその回動中心から偏心した位置に下方に突き出すつまみ部５２を形成させ、このつまみ部を５２利用したキャッチャー部材２の回動により引き込み位置にあるキャッチャー部材２を待機位置に向けて回動させるようにした例を示している。すなわち、この例にあっては、かかるつまみ部５２が前記操作手段５として機能するようになっている。   Further, FIG. 9 shows that the catcher member 2 itself is formed with a knob portion 52 protruding downward at a position eccentric from the rotation center, and the catcher member in the retracted position by the rotation of the catcher member 2 using the knob portion 52. 2 shows an example in which 2 is rotated toward the standby position. That is, in this example, the knob portion 52 functions as the operation means 5.

なお、図示の例では、ピニオン８０に前記スライダ７０にかみ合う側と反対の側（前方）でラックをかみ合わせるダンパー用スライダ１００がケーシング６０の長さ方向に沿う向きにスライド移動可能に支持されていると共に、このダンパー用スライダ１００のケーシング６０の他端６０ｄ側に向けた移動によりピストンロッド１１０ａをシリンダー１１０ｂ内に進入させるピストンダンパー１１０がケーシング６０内に組み込まれており、このピストンダンパー１１０によって待機位置から引き込み位置に向けたキャッチャー部材２の回動に制動を付与して扉Ｍａの移動終了位置に向けた移動がゆっくりとなされるようにしてある。また、ケーシング６０の開放された下面は６０ｊ、ストライカ軸１１の移動軌跡に沿った割溝を備えた図示しない蓋体によって覆われるようになっている。   In the illustrated example, a damper slider 100 that engages the rack on the opposite side (front side) of the pinion 80 to the side engaging the slider 70 is supported so as to be slidable in the direction along the length direction of the casing 60. In addition, a piston damper 110 that causes the piston rod 110a to enter the cylinder 110b by moving the slider slider 100 toward the other end 60d of the casing 60 is incorporated in the casing 60, and the piston damper 110 waits. Brake is applied to the rotation of the catcher member 2 from the position toward the retracted position so that the movement toward the movement end position of the door Ma is slowed down. The opened lower surface of the casing 60 is covered with a lid (not shown) provided with a split groove 60j along the movement locus of the striker shaft 11.

（図１０〜図２０に示される例）
図１０〜図２０は、かかるアシスト装置によって、引き戸Ｍｂの往動（閉じる向きのスライド移動）を、所定移動位置（引き戸Ｍｂが閉じるやや手前の位置）より移動終了位置（引き戸Ｍｂが閉じきった位置）まで補助するようにしてある。図示の例では、可動体Ｍは引き戸Ｍｂであり、固定体Ｓはこの引き戸Ｍｂの戸枠Ｓｃとなっている。また、図示の例では、キャッチャー部材２は引き戸Ｍｂの上部に形成されたこの引き戸Ｍｂの上端面Ｍｃに溝口を配し且つ引き戸Ｍｂの前端Ｍｄにおいて溝一端を外方に開放させた溝状空間Ｍｅ内に内蔵され、これに対応してストライカ部材１は戸枠Ｓｃの戸当たりＳｄ側において、その上枠部Ｓｅにおける引き戸Ｍｂの上端の案内溝Ｓｆの奥部から下方に突き出すように取り付けられている。 (Example shown in FIGS. 10 to 20)
FIGS. 10 to 20 show that the assist device moves the sliding door Mb forward (sliding movement in the closing direction) from the predetermined movement position (sliding door Mb closes slightly before the sliding door Mb is completely closed). To position). In the illustrated example, the movable body M is a sliding door Mb, and the fixed body S is a door frame Sc of the sliding door Mb. Further, in the illustrated example, the catcher member 2 has a groove-like space in which a groove opening is provided on the upper end surface Mc of the sliding door Mb formed at the upper portion of the sliding door Mb and one end of the groove is opened outward at the front end Md of the sliding door Mb. Corresponding to this, the striker member 1 is attached so as to protrude downward from the rear part of the guide groove Sf at the upper end of the sliding door Mb in the upper frame part Se on the door contact Sd side of the door frame Sc. ing.

この例では、ストライカ部材１は、軸上端を前記の位置に取り付けた軸状をなすように構成されている。   In this example, the striker member 1 is configured to have a shaft shape with the upper end of the shaft attached to the above position.

一方、キャッチャー部材２は、前記溝状空間Ｍｅ内に引き戸Ｍｂの移動方向に沿った移動可能に納められている。キャッチャー部材２は、キャッチャー主体２１に対し、上下方向に出没可能に備えられたキャッチャーストッパ２２と、前後動可能に備えられると共に非抱持状態において前方からストライカ部材１を受け入れるストライカ部材１の抱持体２３と、これらの付勢体２４を有している。キャッチャーストッパ２２と抱持体２３とは連係されており、かかる付勢体２４によって、キャッチャーストッパ２２がキャッチャー主体２１より突出されているときには抱持体２３は前進位置にあって非抱持状態にあるようにされ、（図１２）かつ、抱持体２３が後退位置にあって抱持状態にあるときにはキャッチャーストッパ２２はキャッチャー主体２１内に引き込まれるようになっている。（図１５）また、前記溝状空間Ｍｅ内には、突出時のキャッチャーストッパ２２の掛合穴６１ａが形成されており、この掛合穴６１ａにキャッチャーストッパ２２を掛合させたキャッチャー部材２の待機位置において付勢手段３への蓄勢がなされるようになっている。そして、可動体Ｍが自走開始位置まで往動されてきたときに待機位置にあるキャッチャーの抱持体２３内にストライカ部材１が進入されるようになっている。   On the other hand, the catcher member 2 is housed in the groove-like space Me so as to be movable along the moving direction of the sliding door Mb. The catcher member 2 is held by a catcher stopper 22 that can be moved up and down with respect to the catcher main body 21 and a striker member 1 that can be moved back and forth and receives the striker member 1 from the front in a non-holding state. It has a body 23 and these biasing bodies 24. The catcher stopper 22 and the holding body 23 are linked together. When the catcher stopper 22 is projected from the catcher main body 21 by the biasing body 24, the holding body 23 is in the forward movement position and is not held. The catcher stopper 22 is pulled into the catcher main body 21 when the holding body 23 is in the retracted position and in the holding state (FIG. 12). (FIG. 15) Further, a hooking hole 61a of the catcher stopper 22 at the time of protrusion is formed in the groove-like space Me, and in the standby position of the catcher member 2 in which the catcher stopper 22 is hooked into the hooking hole 61a. Accumulation in the urging means 3 is performed. When the movable body M has moved forward to the self-running start position, the striker member 1 is inserted into the holding body 23 of the catcher at the standby position.

所定移動位置に可動体Ｍとしての引き戸Ｍｂを往動させたときに待機位置（図１０の位置）にあるキャッチャー部材２の抱持体２３にストライカ部材１が入り込むと抱持体２３はこれに押されて後退位置に移動されストライカ部材１を抱持捕捉掛合する。抱持体２３が後退位置に移動されるとキャッチャーストッパ２２はキャッチャー主体２１内に引き込まれて掛合穴６１ａとの掛合が解除されることから、固定体Ｓとしての戸枠Ｓｃにストライカ部材１を介して係止されたキャッチャー部材２は付勢手段３の付勢によって相対的に引き込み位置（図１３の位置）に移動され、この付勢力を移動終了位置まで引き戸Ｍｂに作用させるようになっている。移動終了位置から引き戸Ｍｂを復動させるとキャッチャー部材２は再び待機位置まで相対的に移動されキャッチャーストッパ２２は再び付勢体２４の作用により掛合穴６１ａに入り込むと共に、抱持体２３は非抱持状態になりストライカ部材１をリリースする。   When the striker member 1 enters the holding body 23 of the catcher member 2 at the standby position (position in FIG. 10) when the sliding door Mb as the movable body M is moved forward to the predetermined movement position, the holding body 23 It is pushed and moved to the retracted position, and the striker member 1 is held and caught. When the holding body 23 is moved to the retracted position, the catcher stopper 22 is pulled into the catcher main body 21 and the engagement with the engagement hole 61a is released. Therefore, the striker member 1 is attached to the door frame Sc as the fixed body S. The catcher member 2 that is locked through is moved to the retracted position (position of FIG. 13) relatively by the urging of the urging means 3, and this urging force is applied to the sliding door Mb to the movement end position. Yes. When the sliding door Mb is moved backward from the movement end position, the catcher member 2 is relatively moved again to the standby position, and the catcher stopper 22 enters the engagement hole 61a again by the action of the biasing body 24, and the holding body 23 is not held. The striker member 1 is released.

すなわち、この例では、かかるキャッチャーストッパ２２と掛合穴６１ａとにより前記保持手段４を構成させている。   That is, in this example, the holding means 4 is constituted by the catcher stopper 22 and the engagement hole 61a.

そしてこの例では、ストライカ部材１を捕捉しない状態で引き込み位置にキャッチャー部材２が移動された場合、可動体Ｍとしての引き戸Ｍｂを移動終了位置まで往動させると引き込み位置にあって後退位置にあるキャッチャー部材２の抱持体２３がストライカ部材１を抱持捕捉掛合するようになっている。   In this example, when the catcher member 2 is moved to the retracted position without capturing the striker member 1, when the sliding door Mb as the movable body M is moved forward to the movement end position, it is in the retracted position and is in the retracted position. The holding body 23 of the catcher member 2 holds and holds the striker member 1.

すなわちこの例では、抱持体２３は、キャッチャー主体２１に前後動可能に組み合わされたスライド体２３ａと、左右一対の抱持片２３ｂ、２３ｂとを、このスライド体２３ａの前端と抱持片２３ｂの後端との間に亘る樹脂ヒンジ部２３ｃによって一体に連接させて構成されている。それと共に、前記溝状空間Ｍｅを構成するケーシング６０における引き戸Ｍｂの移動方向に沿った内壁の一部に、待機位置にあるキャッチャー部材２の抱持体２３の抱持片２３ｂを入り込ませる切り欠き部６１ｂが形成されていると共に、（図１２）引き込み位置にあるキャッチャー部材２の抱持体２３の抱持片２３ｂの樹脂ヒンジ部２３ｃを中心とした外側への広がりだし、つまり、非抱持状態への移行を弾性的に許容する弾性変形部６１ｃが形成されている。（図１５）待機位置にあるキャッチャー部材２の抱持体２３は前進位置にあって一対の抱持片２３ｂ、２３ｂの内側突出部２３ｄ間にはストライカ部材１の進入を許容する間隔が形成される。（非抱持状態）可動体Ｍが後退位置に移動されると抱持片２３ｂは切り欠き部６１ｂから抜け出させられケーシング６０の内壁によって一対の抱持片２３ｂ、２３ｂは樹脂ヒンジ部２３ｃを弾性変形させてその内側突出部２３ｄ間から前方にストライカ部材１を抜け出させない抱持状態となる。ストライカ部材１を捕捉しない状態で引き込み位置にキャッチャー部材２が移動された場合、キャッチャー部材２の抱持体２３は抱持状態にあるが、前記弾性変形部６１ｃが抱持片２３ｂの外側に位置されることから、引き戸Ｍｂを移動終了位置まで往動させると抱持片２３ｂの内側突出部２３ｄに前方からストライカ部材１を突き当てて弾性変形部６１ｂを変形させながら抱持片２３ｂを外側に一旦開かせ非抱持状態を作り出すことができると共に、ストライカ部材１が内側突出部２３ｄを乗り越えた位置での弾性変形部６１ｃの弾性復帰により抱持体２３を再び抱持状態に移行させてストライカ部材１を抱持捕捉することができる。   That is, in this example, the holding body 23 includes a slide body 23a combined with the catcher main body 21 so as to be movable back and forth, and a pair of left and right holding pieces 23b and 23b, and a front end of the slide body 23a and the holding piece 23b. It is configured to be integrally connected by a resin hinge portion 23c extending between the rear end and the rear end. At the same time, a notch for allowing the holding piece 23b of the holding body 23 of the catcher member 2 at the standby position to enter a part of the inner wall along the moving direction of the sliding door Mb in the casing 60 constituting the groove-shaped space Me. The portion 61b is formed and (FIG. 12) the holding piece 23b of the holding body 23 of the catcher member 2 in the retracted position starts to spread outwardly around the resin hinge portion 23c, that is, is not held An elastic deformation portion 61c that elastically allows transition to a state is formed. (FIG. 15) The holding body 23 of the catcher member 2 in the standby position is in the forward movement position, and an interval allowing the striker member 1 to enter is formed between the inner projecting portions 23d of the pair of holding pieces 23b and 23b. The (Non-holding state) When the movable body M is moved to the retracted position, the holding piece 23b is pulled out of the notch 61b, and the pair of holding pieces 23b and 23b elastically moves the resin hinge 23c by the inner wall of the casing 60. The striker member 1 is held in a state where the striker member 1 is not pulled forward from between the inner projecting portions 23d. When the catcher member 2 is moved to the retracted position without capturing the striker member 1, the holding body 23 of the catcher member 2 is in the holding state, but the elastic deformation portion 61c is positioned outside the holding piece 23b. Therefore, when the sliding door Mb is moved forward to the movement end position, the striker member 1 is abutted from the front against the inner projecting portion 23d of the holding piece 23b, and the holding piece 23b is moved outward while the elastic deformation portion 61b is deformed. It can be opened once and a non-holding state can be created, and the holding body 23 is again shifted to the holding state by the elastic return of the elastically deforming portion 61c at the position where the striker member 1 gets over the inner protrusion 23d. The member 1 can be held and captured.

固定体Ｓとしての戸枠Ｓｃに対する可動体Ｍとしての引き戸Ｍｂの組み付けないし組み合わせ状態に狂いなどが生じている場合、引き戸Ｍｂを移動終了位置まで移動させても引き込み位置にあるキャッチャー部材２の抱持体２３を構成する左右一対の抱持片２３ｂ、２３ｂ間にストライカ部材１を入り込ませることができなくなる。（図１６）この例にかかるアシスト装置にあっては、このような場合でも、操作手段５によって、キャッチャー部材２の抱持体２３を構成する左右一対の抱持片２３ｂ、２３ｂ間にストライカ部材１が入り込む位置まで、前記狂いなどの寸法分キャッチャー部材２を待機位置に向けて回動させることができる。   When there is an error in the assembled or combined state of the sliding door Mb as the movable body M with respect to the door frame Sc as the fixed body S, the holding of the catcher member 2 in the retracted position even if the sliding door Mb is moved to the movement end position. The striker member 1 cannot be inserted between the pair of left and right holding pieces 23b, 23b constituting the holding body 23. (FIG. 16) In the assist device according to this example, even in such a case, the striker member is interposed between the pair of left and right holding pieces 23b, 23b constituting the holding body 23 of the catcher member 2 by the operating means 5. The catcher member 2 can be rotated toward the standby position by the dimension such as the deviation until the position where 1 enters.

図１７及び図１９は、かかる操作手段５を、引き込み位置にあるキャッチャー部材２のキャッチャー主体２１の後端部２１ａに周面を接しさせるようにこのケーシング６０に支持された裁頭円錐状体５３として構成した例を示している。   17 and 19 show that the operating means 5 has a truncated conical body 53 supported by the casing 60 so that its peripheral surface is in contact with the rear end 21a of the catcher main body 21 of the catcher member 2 in the retracted position. An example configured as shown in FIG.

図１７の例では、かかる裁頭円錐状体５３は、ケーシング６０の引き戸Ｍｂの移動方向に沿った内壁間にこの移動方向に直交する向きの移動可能に支持されていると共に、一方の内壁側へのバネ５３ａによる付勢を受けた状態で位置づけられている。かかる裁頭円錐状体５３は、引き戸Ｍｂとケーシング６０とを貫通する操作用孔５３ｂを通じて、軸状工具により前記バネ５３ａの付勢に抗して押し込むことができるようになっている。そしてこのように押し込まれると裁頭円錐状体５３の拡径側の周面がキャッチャー主体２１の後端部２１ａに接し引き込み位置にあるキャッチャー部材２を前記付勢手段３の付勢に抗して引き戸Ｍｂの前端Ｍｄ側に移動させるようになっている。   In the example of FIG. 17, the frustoconical body 53 is supported between the inner walls along the moving direction of the sliding door Mb of the casing 60 so as to be movable in a direction perpendicular to the moving direction, and on one inner wall side. It is positioned in a state where it is biased by the spring 53a. The frustoconical body 53 can be pushed against the bias of the spring 53a by an axial tool through an operation hole 53b penetrating the sliding door Mb and the casing 60. When pushed in this way, the peripheral surface on the enlarged diameter side of the truncated cone 53 comes into contact with the rear end portion 21a of the catcher main body 21 so that the catcher member 2 in the retracted position resists the biasing of the biasing means 3. The sliding door Mb is moved to the front end Md side.

図１９の例では、かかる裁頭円錐状体５３は、ケーシング６０の引き戸Ｍｂの移動方向に沿った内壁間にこの移動方向に直交する向きの移動可能に支持されていると共に、その円心に設けられた雄ねじ体５３ｃをケーシング６０に形成させた雌ネジ孔５３ｄにネジ付けている。かかる雄ねじ体５３ｃは、引き戸Ｍｂとケーシング６０とを貫通する操作用孔５３ｂを通じて、工具などにより操作できるようになっている。そして雄ネジ体５３ｃを操作すると裁頭円錐状体５３の拡径側の周面がキャッチャー主体２１の後端部２１ａに接するようにでき、これにより引き込み位置にあるキャッチャー部材２を前記付勢手段３の付勢に抗して引き戸Ｍｂの前端Ｍｄ側に移動させるようになっている。   In the example of FIG. 19, the frustoconical body 53 is supported between the inner walls along the moving direction of the sliding door Mb of the casing 60 so as to be movable in a direction orthogonal to the moving direction, and at the center thereof. The provided male screw body 53 c is screwed into a female screw hole 53 d formed in the casing 60. The male screw body 53c can be operated by a tool or the like through an operation hole 53b that penetrates the sliding door Mb and the casing 60. When the male threaded body 53c is operated, the peripheral surface on the enlarged diameter side of the truncated cone 53 can be brought into contact with the rear end portion 21a of the catcher main body 21, whereby the catcher member 2 in the retracted position can be urged. 3 is moved to the front end Md side of the sliding door Mb against the urging force 3.

また、図１８の例では、かかる操作手段５を、引き込み位置にあるキャッチャー部材２のキャッチャー主体２１の後端部２１ａに周面を接しさせるようにこのケーシング６０に支持された円筒体５４として構成した例を示している。   Further, in the example of FIG. 18, the operation means 5 is configured as a cylindrical body 54 supported by the casing 60 so that the peripheral surface is in contact with the rear end portion 21 a of the catcher main body 21 of the catcher member 2 in the retracted position. An example is shown.

かかる円筒体５４は、ケーシング６０の引き戸Ｍｂの移動方向に沿った内壁間にこの移動方向に直交する向きの移動可能に支持されていると共に、その支持軸５４ａを円心から偏心した位置に有しており、引き戸Ｍｂとケーシング６０とを貫通する操作用孔５３ｂを通じて支持軸５４ａを工具などにより操作できるようになっている。そして支持軸５４ａを操作してこの支持軸５４ａから離れた側の円筒体５４の周面がキャッチャー主体２１の後端部２１ａに接するようにでき、これにより引き込み位置にあるキャッチャー部材２を前記付勢手段３の付勢に抗して引き戸Ｍｂの前端Ｍｄ側に移動させるようになっている。   The cylindrical body 54 is supported between the inner walls along the moving direction of the sliding door Mb of the casing 60 so as to be movable in a direction orthogonal to the moving direction, and has a support shaft 54a at a position eccentric from the center of the circle. The support shaft 54a can be operated with a tool or the like through an operation hole 53b that passes through the sliding door Mb and the casing 60. Then, by operating the support shaft 54a, the peripheral surface of the cylindrical body 54 on the side away from the support shaft 54a can be brought into contact with the rear end portion 21a of the catcher main body 21, whereby the catcher member 2 in the retracted position can be attached. The sliding means Mb is moved to the front end Md side against the biasing force of the biasing means 3.

また、図２０の例では、かかる操作手段５を、キャッチャー部材２のキャッチャー主体２１の後端部２１ａへの接続部５５ａと、この接続部５５ａにおける引き戸Ｍｂの上端面Ｍｃから側方に突き出す箇所より下方に垂下する操作部５５ｂとを備えた操作片５５として構成した例を示している。このようにした場合には、かかる操作片５５を利用して引き込み位置にあるキャッチャー部材２を前記付勢手段３の付勢に抗して引き戸Ｍｂの前端Ｍｄ側に直接的に移動させることができる。   Moreover, in the example of FIG. 20, the operation means 5 is a portion protruding sideways from the connecting portion 55a to the rear end portion 21a of the catcher main body 21 of the catcher member 2 and the upper end face Mc of the sliding door Mb in the connecting portion 55a. The example comprised as the operation piece 55 provided with the operation part 55b drooping further downward is shown. In this case, the catcher member 2 in the retracted position can be moved directly to the front end Md side of the sliding door Mb against the urging force of the urging means 3 using the operation piece 55. it can.

図示の例では、キャッチャー部材２は、引き戸Ｍｂの上部に内蔵されて内部を前記溝状空間Ｍｅとするケーシング６０に前記移動を可能とした状態で組み合わされ納められている。ケーシング６０は上面を開放させた細長い箱状をなすように構成されている。ケーシング６０は仕切り部６１ｄにより上下に区分されており、この仕切り部６１ｄに前記掛合穴６１ａが形成されている。また、仕切り部６１ｄの下方には付勢手段３としての引っ張りコイルバネ３１が内蔵されている。このバネ３１のバネ一端３１ａはキャッチャー部材２のキャッチャー主体２１に止着され、バネ他端３１ｂはケーシング６０における引き戸Ｍｂの後端側に位置される端部に止着されている。そして、キャッチャー部材２が待機位置にある状態においてこのバネ３１がもっとも引き延ばされるようになっている。引き戸Ｍｂを所定移動位置まで往動されるとキャッチャー部材２はストライカ部材１をキャッチして停止すると同時に保持手段４の保持が解除されることからバネ３１の付勢により引き戸Ｍｂが移動終了位置まで移動し溝状空間Ｍｅ内でキャッチャー部材２は引き込み位置に相対的に移動される。移動終了位置にある引き戸Ｍｂが所定移動位置まで復動されるとキャッチャー部材２はバネ３１に蓄勢させながら待機位置まで相対的に移動されてストライカ部材１をリリースすると同時に保持手段４により待機位置に位置づけられる。   In the illustrated example, the catcher member 2 is combined and housed in a casing 60 that is built in the upper part of the sliding door Mb and has the inside as the groove-shaped space Me so as to allow the movement. The casing 60 is configured to have an elongated box shape with the upper surface opened. The casing 60 is vertically divided by a partition portion 61d, and the engagement hole 61a is formed in the partition portion 61d. In addition, a tension coil spring 31 as the biasing means 3 is incorporated below the partition portion 61d. One end 31 a of the spring 31 is fixed to the catcher main body 21 of the catcher member 2, and the other end 31 b of the spring is fixed to an end portion of the casing 60 positioned on the rear end side of the sliding door Mb. The spring 31 is extended most when the catcher member 2 is in the standby position. When the sliding door Mb is moved to a predetermined movement position, the catcher member 2 catches the striker member 1 and stops, and at the same time, the holding means 4 is released, so that the spring 31 biases the sliding door Mb to the movement end position. The catcher member 2 moves and moves relative to the retracted position in the groove-like space Me. When the sliding door Mb at the movement end position is moved back to the predetermined movement position, the catcher member 2 is moved relatively to the standby position while accumulating the spring 31 to release the striker member 1 and at the same time by the holding means 4. Is positioned.

なお、図示の例では、キャッチャー部材２のキャッチャー主体２１の後端部２１ａに、このキャッチャー部材２の引き込み位置に向けた相対的な移動によりピストンロッド１１１ａをシリンダー１１１ｂ内に進入させるピストンダンパー１１１がケーシング６０内に組み込まれており、このピストンダンパー１１１によって待機位置から引き込み位置に向けたキャッチャー部材２の相対的な移動に制動を付与して引き戸Ｍｂの移動終了位置に向けた移動がゆっくりとなされるようにしてある。   In the illustrated example, a piston damper 111 that causes the piston rod 111a to enter the cylinder 111b by a relative movement toward the retracted position of the catcher member 2 is provided at the rear end portion 21a of the catcher main body 21 of the catcher member 2. Built in the casing 60, the piston damper 111 applies braking to the relative movement of the catcher member 2 from the standby position toward the retracted position, and the movement toward the movement end position of the sliding door Mb is slowed down. It is made to do.
